^ Orange-red, ivith hlackish hordcrs. Forc-iving : border rather 

 narrow at base (wliere it is suffused with greyish-yellow-ochreous, 

 which sometimes uan-owly edges costa to apex), but widening greatly 

 to apex, whence, abruptly narrowing on third median nervule, it is 

 moderately broad along hind-margin to j^osterior angle, where it 

 usually widens again ; base blackish mixed with ochreous. Hind- 

 wing : border sometimes nearly obsolete ou costa, but in many Cape 

 Town examples rather broad ; always developed very broadly about 

 apex, narrowed abruptly on third median nervule, and thence only a 

 dentate edging to anal angle. Under side. — Hind-wing and hordcr 

 of fore-wing greyish or hroivnish ochreous, or often 2^U7ylish-lc(Jce, the 

 former icith irregular whitish streaks and sjwts. Fore-wing: orange 

 usually paler, especially towards inner margin, which is bordered with 

 whitish ; two black spots in cell, one closing it ; an inwardly-oblique, 

 transverse, bi-angulated row of five or six beyond it, and a suffused 

 submarginal row, — all spots above median nervure and its first branch 

 silvery- white centred, those of cell very conspicuously ; below . cell two 

 blackish markings (one basal, one just beyond), usually confluent. 

 Hind-iving : two small spots at base, one on costa, one iu cell ; a 

 transverse row of four before middle (one in cell) ; a long streak closing 

 cell, usually confluent inferiorl}^ with a most irregular, very sharply 

 dentated, more or less suffused transverse stripe immediately succeeding 

 it ; a small spot touching costal nervure about middle ; a submarginal 

 dentated streak, often indistinct, always so towards costa. In both 

 wings a rather indistinct hind-marginal row of spots, sometimes in- 

 teriorly bordered by some whitish marks. Cilia blackish, interrupted 

 with white between nervules. 



^ Oretnge nsucdly rcdlier ixdcr and duller, horder not so dark ; 

 ochreous basal suffusion usually much broader. Fore-wing : at outer 

 and upper edge of orange there is often an upward projection of that 

 colour as far as first radial nervule ; border often very broad at 

 posterior angle. Hind-iving : apical border usually broader than in 

 ^ ; usually a suffused blackish spot between first median nervule and 

 submedian nervure near anal angle. Under side. — As in ^. 



This species is very variable, chiefly in the colour of under side 

 of hind-wing and the distinctness of its markings, but also in the 

 extent and tint of the orange of upper side, which in some specimens 

 is very limited in extent, in others very broad. I have no doubt of 

 this being the true Thyra of Linne, having taken one specimen near 

 Cape Town which answers in every particular to the details given in 

 " Museum Ludovicee, &c." In the majority of examples the under- 

 side markinafs are not so bright as Linn^ notes them.
